repo-onboarding-context-map

repo-onboarding-context-map is a skill for Claude Code, Codex from fusebase-dev/fusebase-flow. It costs 47 tokens per session (1,250 once invoked), scanned A, original, MIT.

A first-time guide for inspecting an unfamiliar code repository and recording its structure, commands, protected files, and risky boundaries in a durable context map.

In plain words
What is it for?
Use it when taking over an unfamiliar repository, setting up the workflow there, or refreshing context after a framework change, split, or large rename.
Why use it?
It saves future sessions from repeating the same repository investigation and makes important safety limits visible. It is intended for new installations or major structural changes, not routine bug work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

repo-onboarding-context-map scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repo Onboarding & Context Map

Purpose

Inspect an unfamiliar repo and produce a durable context map so future sessions know the project's structure, commands, protected paths, and risky system boundaries without re-investigating each session.

Named reader: workflows/session-initiation.md step 5 — every new session reads docs/specs/repo-context.md when it exists and is <90 days old, instead of re-investigating. The map header MUST carry Generated: <YYYY-MM-DD> so readers can apply the freshness gate.

When to invoke

  • First-time installation of Fusebase Flow into an existing repo
  • Operator says "I'm picking up this repo" / "what's in this codebase?" / "set up flow here"
  • After a major structural change (large rename, monorepo split, framework swap)
  • When docs/specs/repo-context.md is missing or older than 90 days

Do not invoke when

  • A current repo-context.md exists and the repo hasn't changed structurally
  • Operator is asking a code-specific question — use code-review or normal investigation
  • A spec is in flight — don't pivot to onboarding mid-ticket

Required inputs

Input Where it lives If missing
Repo root git root Stop; ask operator to confirm working directory
Package/project files package.json, pyproject.toml, Cargo.toml, etc. Note "no manifest detected"; describe based on file extensions only
Existing READMEs README.md, docs/, etc. Note absence; flag as Phase-4 onboarding gap
CLI edition map, for this edition docs/fusebase-cli-edition.md Continue with generic repo map, but mark CLI provider asset mapping unknown

Procedure

  1. List repo root files (top level only). Identify project type (Node/Python/Go/Rust/etc.) and frontend/backend split if visible.
  2. Read root README.md if present. Read up to 3 most-referenced docs in docs/.
  3. If this is the Fusebase CLI edition or a downstream Fusebase Apps project, read docs/fusebase-cli-edition.md and record which CLI provider assets are present and relevant.
  4. Detect build/test/lint commands from manifest files. Capture exact commands.
  5. Identify protected-path candidates: long-lived worker code, generated files, migration files, deployment configs.
  6. Identify risky system boundaries: external APIs, database migrations, auth surfaces, file system writes outside repo.
  7. Run git log --oneline -30 to read commit cadence + recent areas of activity.
  8. Save findings to docs/specs/repo-context.md using templates/spec.md adapted for context-mapping (see template). Stamp a Generated: <YYYY-MM-DD> line in the header — workflows/session-initiation.md step 5 uses it for the 90-day freshness gate.
  9. Propose updates to AGENTS.md "project-specific values" section. Show the diff in chat. Do NOT apply unless operator says "apply".
  10. Propose initial policies/protected-paths.yml candidates. Save as draft if operator approves; do NOT auto-write.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
